In order to develop the high performance tire rubber materials that will become increasingly essential in the near future, we must first return to square one and consider how rubber performance traits are manifested. Thus, it will be necessary for us to elucidate and understand the internal structures and mechanisms of rubber at the micrometer and even the nanometer scale. Sumitomo Rubber Industries Ltd. has developed our New Materials Development Technology: “Advance 4D nano design.”
It makes use of the advanced technologies of the K computer and other cutting-edge equipment such as SPring-8, J-PARC in Japan, enabling the analysis of rubber chemicals at a molecular level.
In this paper, some cases of development of rubber, including the development of high strength rubber to improve wear resistance using large scale simulation, will be described.
